Title: Apparatus for determining the quantity of milk delivered by a cow and for drawing a sample from the milk delivered
IPC: A01J5/01
Filed: 1975-09-01
Abstract: 1489705 Weighing apparatus P P KIESTRA 1 Sept 1975 [6 Sept 1974] 35943/75 Heading G1 [Also in Division B8] An apparatus for determining the quantity of milk delivered by a cow and taking a sample of the milk comprises a frame 1 having an upper wall 2, a milk container 4 suspended from wall 2 by springs 3 and having an upper edge 5 engageable against wall 2 via a seal 6, an inlet 7 and a chamber 9 for connection to a milking cluster and to milk storage suction conduit 8 respectively, a tube 10 extending from wall 2 to near the bottom of the container, a valve 11 adjustable selectively to place tube 10 in communication with chamber 9 or the atmosphere, a valve 12 controlling the connection between container 4 and chamber 8, indicating means responsive to the vertical position of the container when suspended by the springs, and means for taking a sample of the milk being delivered through the chamber to the conduit 8. In use, with valves 11, 12 open as in Fig. 1, milk is sucked into container 4, and container 4 is held against seal 6 by the effects of springs 3 and the suction. At the end of the milking operation, valve 11 is closed, and air is sucked through valve 11 tube 10 and the milk in container 4 to thoroughly mix the milk, Fig. 2 (not shown). At the end of the mixing operation, valve 12 is closed, the vacuum in container 4 is broken, and container 4 drops and is supported by springs 3 only, the position of the container being determined by the weight of milk. A rod 33, Fig. 6, drives a drum 31 via a rack and pinion 29, 30, and graduations on drum 31 are projected on to a camera 32. Camera 32 is also arranged to record an identification number magnetically coded on to a stainless steel band on the cow's leg. After weighing, the container 4 is emptied by opening valve 11, Fig. 4. The connection 8 includes a constriction 17, and conduits 18, 19 either side of the constriction are connected to conduits 21, 22 of a sample bottle 20. Sample bottle 20 has a valve 25 which, in a first position Fig. 7, closes the bottom of the bottle but opens conduits 21, 22 so that a flow of milk into and through the bottle occurs, and a second position closes conduits 21, 22 and opens the bottom of the bottle to allow the milk to drain into container 27. A rotary table indexed automatically and carrying a plurality of containers 27 may be provided. When all the milking operations have been signals carried out, valves 11, 12 may be opened for rinsing and cleaning operations, Fig. 5 (not shown). Valve 25 may be opened to clean bottle 20. A program controller may be provided to control the valves as required.

Title: Improvements relating to the preparation of dough
IPC: A21D2/36
Filed: 1929-11-23
Abstract: Dough is prepared by a two-stage process as follows: in the first stage a mixture comprising flour and water (with or without yeast and/or additional materials usual in making a sponge) is, after uniform incorporation, subjected to a further treatment by the action of high speed beaters or blades until the batter tightens or acquires an increased consistency; in the second stage the remaining ingredients of the dough batch are incorporated by the usual slow-speed mixers with the sponge or batter produced in the first stage.  A small proportion of an auto-oxidizable substance, such as soya bean flour, haricot bean flour, pea flour or lentil flour, or an extract or suspension of such flour or flours, may be incorporated in the mixture for the first stage of the process.  Specification 342,697 is referred to.

Title: Process of reducing sulphate content in stock feed
Inventor: PHILLIPS ROBERT JAMES
Filed: 1960-10-21
Abstract: 950,748. Electrostatic precipitation. HOWEBAKER ENGINEERS Inc. Oct. 21, 1960, No. 36126/60. Heading B2J. A process of treating hydrocarbon streams containing sulphur includes intimately and vigorously admixing sulphuric acid with the stream to reduce the acid to a particle size which increases the surface area of the acid available for contact with the sulphur to initiate the oxidation reaction of the sulphur to the disulphide form which is soluble in the acid and conducting the acid hydrocarbon mixture into a settling zone of an electrostatic precipitator. The acid hydrocarbon mixture is retained in the zone to permit further chemical reaction of the sulphur and acid to proceed to produce further disulphides, the retention of the mixture in the settling zone also allowing precipitation of some acid containing disulphide form reation products produced in the first reaction. The mixture is then passed through at least one electrical field zone in the electrostatic precipitator wherein the electrical field is generated by a direct current of 1900-2500 volts per inch of electrode spacing, the electrode spacing being between 6 and 12 inches to produce further chemical reaction to complete the conversion of the sulphur to disulphides and to ensure coalescence and precipitation of the acid and disulphide. Finally the acid is removed from the settling zone and the desulphurized hydrocarbon stream conducted from the electrical field zone of the electrostatic precipitator. The hydrocarbon stream, which may be the naptha fractions of petroleum, is passed into a mixer with rotatable blades where it is mixed with the sulphuric acid so that the reaction can start the reaction products entering into solution with the sulphuric acid. The stream is now passed upwardly through an electrostatic precipitator to precipitate the acid and reaction products in solution. The acid if not spent is recirculated. A float maintains the desired liquid level in the precipitator which comprises grid electrodes 29, Fig. 2, suspended by conducting rods 30 from bar 31 and earthed grids 32, 33. Baffles 34 confine the hydrocarbon stream to the electrodes. The precipitator electrodes are energized by D.C. but a rectified three phase current is used, and the precipitator is at a temperature of 40-150 ‹F. The hydrocarbon stream is admitted by a multiapertured pipe 27. The stream from the first precipitator is mixed with NaOH and fed to a second precipitator, excess NaOH being recirculated and a third precipitator effects a water wash. It is stated that nitrogen compounds are also removed or reduced.

[Also in Group XL (c)] A circuit for detecting a transient change in the magnification factor of an oscillatory circuit connected in the input of an oscillator comprises a rectifying circuit which is fed from the output of the oscillator to provide a delayed A.V.C. voltage which is fed-back to the input of the oscillator with a delay time longer than the time of the transient change in the magnification factor and means for detecting or measuring transient changes in the output voltage of the oscillator. The Figure shows a circuit for detecting the presence of a metal or of a metallic impurity in a material which is passed between the plates of a capacitor 2 or into the coil of an inductor 1 which form the tuned circuit of an oscillator comprising stages 4, 7 having positive-feed back between them via capacitor 18. The change in the magnification factor (Q) of tuned circuit 1, 2 produces a change in the oscillatory voltage level across terminals 20, 21 which maybe measured or detected. Part of the output voltage from stage 7 is rectified by rectifiers 11 and the resulting D.C. voltage is applied as delayed A.V.C. to the grid circuits of stages 4 and 7. The delay circuit 14, 15 has a delay time which is longer than the time of the transient changes which occur in the oscillator when a change in the Q of circuit 1, 2 takes place. The resistor 19 and the equivalent resistance of the circuit 1, 2 have values such that normally the gain round the feed-back loop is unity.
